Acting on paired donors, with incorporation or reduction of molecular oxygen;
With reduced flavin or flavoprotein as one donor, and incorporation of one atom of oxygen into the other donor
Sysname
flavonoid,[reduced NADPH---hemoprotein reductase]:oxygen oxidoreductase (3'-hydroxylating)
Reaction(IUBMB)
a flavonoid + [reduced NADPH---hemoprotein reductase] + O2 = a 3'-hydroxyflavonoid + [oxidized NADPH---hemoprotein reductase] + H2O [RN:R03615]
Reaction(KEGG)
Substrate
flavonoid [CPD:C01579];
[reduced NADPH---hemoprotein reductase] [CPD:C03024];
O2 [CPD:C00007]
Product
3'-hydroxyflavonoid [CPD:C02790];
[oxidized NADPH---hemoprotein reductase] [CPD:C03161];
H2O [CPD:C00001]
Comment
A cytochrome P-450 (heme-thiolate) protein found in plants. Acts on a number of flavonoids, including the flavanone naringenin and the flavone apigenin. Does not act on 4-coumarate or 4-coumaroyl-CoA.
